I used to travel on the road a lot for work. Kept a lot of basic emergency tools and gadgets in my trunk to get me out of hot water.
There is an old standby to pump a tire that was small and potent and didn’t require charging. It was sold in sports stores. The “Franklin” foot pump. Used to pump basketballs, footballs, bike tires and even car tires. It’s still around. I bought one last year.
Also, I kept multiple aerosol canisters of foam tire inflaters in the trunk. A quick temporary fix to get the rim at least halfway off the ground. It got you home or to a service station. And, if you had no time to change the damsel-in-distress’s tire, you could squirt some of your foam inside her — I mean inside her tire. I carried extras to help distressed motorists as well as myself.
Also, I used to get rid of the doughnut tire and go to the Roosevelt Avenue Dumps across from Citifield and buy a used rim and practically new tire off of a wrecked vehicle. If I had time, I would just change the tire if I had an emergency flat and drive the flat tire to the service station and have a plug put into the flat tire.
I used to roam the aisles of R&S Strauss, Auto Barn, other auto stores, even Walmart, and buy Lukas additives and the like, to keep the old truck or car going. Also, jumper cables, and a good high-powered battery boost, flashlight, easy lug wrench, easy jack, WD-40, couple of cans of oil
Also kept one of those plastic attache cases with car emergency tools, emergency lighted triangle, first-aid gear, duct tape, rope.
Now I keep a good mini high powered battery charger and air pump with USB’s and attachments to charge the phone.
Years ago, they used to sell a box of gas powder. You added water to the powder and you had temporary fuel. It wasn’t perfect and it got stale and lost potency if not used. Don’t see it anymore.
One Jeep I had, came with an external heavy gauge steel gas can that was attached to the back of the truck extra fuel. Maybe deemed dangerous, but many trucks had external extra fuel tanks and spare tires hanging off the back rear gate of the vehicle.
Also carried non perishable food items and water. (home made Pemmican — LOL)
Some of you “silver foxes” might remember the old days of jacking up the car chassis with a notorious “bumper jack.” Dangerous fickle device that maimed many.
